calculator numerically estimates instead of giving exact value #2240

Numworks calculator provides a numerical estimate when integrating

screenshot screenshot (1) screenshot (2)

Expected behavior

The answer on the third screenshot should be 0 as k=8 satisfies the original equation and when done on paper it is correct but when checking answers on the calculator it provided a numerical estimate rather than the correct answer

Environment

Simulator version: 23.2.1 calculator version: 23.2.3 happens on the simulator and physical calculator

Analytical solutions for arbitrary integrals are often impossible to obtain. Most integrals do not have closed-form solutions, making numerical methods necessary in many cases.
